1999-12-09 13:51  trigg

	* weka/classifiers/Evaluation.java (1.23): - Main utility method no

	* weka/filters/: AddFilter.java (1.6), AttributeFilter.java (1.4),
	NominalToBinaryFilter.java (1.8), NormalizationFilter.java (1.2): -

1999-12-09 11:17  trigg

	* weka/core/Instance.java (1.4): - Added a method to get the
	attribute values as a double array, and added a warning in the

	Instances.FILE_EXTENSION

1999-12-08 14:17  trigg

	* weka/gui/SetInstancesPanel.java (1.5): - Uses
	Instances.FILE_EXTENSION

1999-12-08 14:17  trigg

	CostSensitiveClassifierSplitEvaluator.

1999-12-08 14:15  trigg

	* weka/experiment/CostSensitiveClassifierSplitEvaluator.java (1.2):
	- Uses average cost and total cost measures. Changed to use
	suggested cost file extension CostMatrix.FILE_EXTENSION.

1999-12-08 14:12  trigg

	* weka/core/Instances.java (1.16): - Added a public member for the
	suggested filename extension for arff files.

	suggested cost file extension CostMatrix.FILE_EXTENSION.

1999-12-08 14:10  trigg

	* weka/classifiers/CostMatrix.java (1.4): - Changed to permit
	non-zero diagonal cost entries. Added a normalize method to convert
	to a matrix with zero valued diagonal entries.

1999-12-08 14:08  trigg

	* weka/classifiers/Evaluation.java (1.22): - Changed handling for
	cost-sensitive evaluation. Confusion matrix no longer includes cost
	factors (too confusing), similar with true/false positive rates. 
	Replaced non-intuitive correct/incorrect with cost with average
	cost and total cost. Command line option -m now only specifies
	cost-sensitive evaluation, for cost-sensitive prediction use one of
	the cost-sensitive meta schemes.


1999-12-06 15:52  eibe

	* weka/classifiers/DecisionStump.java (1.9): Fixed bug that
	produced incorrect decision stumps for nominal attributes when the
	class is nominal and missing values are present.

1999-12-06 13:20  trigg

	* weka/experiment/AveragingResultProducer.java (1.4): - Removed
	repeated code.

	(1.8), explorer/AttributeSelectionPanel.java (1.9),
	explorer/ClassifierPanel.java (1.20), explorer/ClustererPanel.java
	(1.10), explorer/PreprocessPanel.java (1.12): - Changed
	FileChoosers to default to the current directory rather than user's
	home (on Mac and NT, where the user's home is often nowhere near
	anything useful, the current directory makes much more sense. The
	user's home is still only one click away).

1999-12-06 10:10  trigg

	* weka/: experiment/CostSensitiveClassifierSplitEvaluator.java
	(1.1), gui/GenericObjectEditor.props (1.8): - Added a classifier
	split evaluator that performs cost-sensitive evaluation.

1999-12-06 10:09  trigg

	* weka/classifiers/: CostSensitiveClassifier.java (1.2),
	Evaluation.java (1.21), MetaCost.java (1.2): - Changed cost file
	handling for cost-sensitive classifiers to support experiments
	across multiple datasets. Cost files can now be loaded "on-demand"
	where a specified directory will be searched for a cost file named
	with the relation name plus ".cost". Added a method to Evalution to
	return the average cost.

1999-12-02 19:34  trigg

	* weka/: classifiers/Makefile (1.8), classifiers/MetaCost.java
	(1.1), gui/GenericObjectEditor.props (1.7): - Implemented MetaCost,
	first version. Modified Makefile and gui property file accordingly.

1999-12-02 19:33  trigg

	* weka/classifiers/Bagging.java (1.9): - Added an option for
	resamples to be a different size to the input training set (for
	superlinear schemes, reducing this can give large speedups).

1999-12-02 19:32  trigg

	* weka/classifiers/CostMatrix.java (1.3): - Added a method to
	generate a default cost matrix for a set of instances that weights
	errors proportional to the ratio of the predicted to actual class
	(i.e. higher cost for predicting a rare class as a common class)

1999-12-02 19:30  trigg

	* weka/classifiers/Evaluation.java (1.20): - Removed debugging
	output of cost matrix

1999-12-02 19:29  trigg

	* weka/classifiers/DistributionClassifier.java (1.3): - Fixed typo

1999-12-02 19:29  trigg

	* weka/classifiers/CheckClassifier.java (1.9): - Fixed bug in
	testing whether test class vals are ignored (I think this was only
	due to an earlier change in Instances)

1999-12-02 19:27  trigg

	* weka/core/Matrix.java (1.4): - Made serializable, so
	cost-sensitive classifiers can be serialized properly

	attributes with only one distinct value.

1999-11-30 16:52  eibe

	* weka/core/AttributeStats.java (1.1): Made AttributeStats a
	separate public class.

1999-11-30 16:51  eibe

	* weka/core/: Instances.java (1.15), Makefile (1.5): Made
	AttributeStats public class.

1999-11-30 16:32  eibe

	* weka/filters/NominalToBinaryFilter.java (1.7): No longer creates
	two dummy attributes for original binary attribute in datasets with
	a nominal class.

1999-11-30 15:51  trigg

	* weka/: Makefile (1.16), classifiers/Makefile (1.7), gui/Makefile
	(1.6): - Changed makefiles to allow using alternatives to javac.
	eg: make all JAVA=jikes

1999-11-30 15:24  eibe

	* weka/classifiers/Logistic.java (1.6): 1. Fixed bug that made
	results for nominal datasets meaningless.  2. Included proper ridge
	estimator to avoid singularities.

	how field widths are set.

1999-11-29 10:27  mhall

	* weka/gui/explorer/AttributeSelectionPanel.java (1.8): Changed so
	that results list shows seach + evaluator, rather than evaluator +
	search.

1999-11-29 10:26  mhall

	* weka/experiment/DatabaseUtils.java (1.6): Increased max string
	size to 300 chars.

	* weka/experiment/: AveragingResultProducer.java (1.3),
	CrossValidationResultProducer.java (1.3),
	DatabaseResultProducer.java (1.4), InstanceQuery.java (1.4),
	RandomSplitResultProducer.java (1.3), ResultProducer.java (1.2):
	Added a doRunKeys method to assemble just the keys for a run. Fixes
	the problem of results being regenerated for stuff that is already
	in a database.

1999-11-26 16:33  mhall

	* weka/gui/PropertySheetPanel.java (1.2): Can now display global
	information about the target object as well as individual tip text
	for each property. Editable objects need to have a public String
	globalInfo() method and a TipText() method for each editable
	property. Eg, if some class has get/setBlah() then it needs a
	public String blahTipText() method. Still works fine for classes
	that don't have these methods.
